EQUILIBEATED DEVICE FOR TRANSFORIVLIIIG INTO CIRCULAR- MOTION THE LINEAR 'II-Ill PISTON OF A MOTOR.

MOTION or Original application filed July 10, 1920, Serial T0 aZZ whom it may concern.

Be it known that 1, Jones Lnnor, citizen of the Republic of France, and residing at Paris, France, 12 Rue Joi'lfl'roy, have in vented an Improved Equilibrated Device or Tlransforming into Circular Motion the Liuearllfotion of the Piston of a Motor.

The mechanism which forms the object of the present invention is characterized by the employment of driving and inversely compensating eccentrics and of counterweights possessing a motion parallel with but inversely to that of the parts to be counterbalanced, so that to each moving part there corresponds an equal weight possessing the inverse motion which compensates the effects of inertia in the motor system.

In order to render intelligible the description, the invention is illustrated in the accompanying drawings as follows:

Fig. 1 shows a sectional elevation of the improved device in question.

Fig. 2 shows a sectional elevation on the line iL-II of Fig. 1.

Fig. 3 shows a sectional elevation of a modification of the said device.

In the improved device according to the present invention use is made of a straight shaft 73 hearing a fly wheel 74.: and two parallel plates 75, 76 each of which bears an eccentric 77 on which are mounted ball bearings. These bearings each travel in the collars 78, 79 each provided with an eyelet 80, 81, in which there engages an axle 82.

This axle 82 passes through a sliding piece 83 which moves between two lates 8%, 85, the said sliding piece being rigidly connected to the piston of the motorby means of a rod 88.

The amount of eccentric motion thus obtained is equal to the stroke of the piston and the operation of the device is as follows:

The action of the motor piston during its downward course, is transmitted by means of the rod 88 to the sliding piece 83 causing this latter to move accordingly and carry with it the axle 82, together with the bearings 7 8, 79. This compels the eccentric to make a half revolution; the following half revolution is effected under the action of the traction of the piston rod during the upward course of this latter.

In order to ensure the equilibrium of the device in question the parallel plates 75, 7 6

bear upon their outer faces. eccentrics 89 keyed at 180 with regard to the former ec centrics 77 and provided in like manner with ball bearings.

The eccentrics 89 control the balance weights 90 travelling in the guides 91. The entire weight of these balancing pieces is equal to the total weight of the axle 82, the sliding piece 83, the rod 88 and the two pistons.

By referring to Figure 3 it may be seen that the balancing of the mechanism transforming the rectilinear motion of the piston into circular action is effected by means of a single counter weight 158 connected to ball races 159, 160 by means of a fork 161. This single balance weight slides in the same sliding grooves 162 as the part 164.

This improvement effects an important simplification of the previous device which required two side counter weights each slidin in special grooves.

laving now particularly described the nature of my invention, and in what manner the same is to be performed what I claim is:

1. In a motor, the combination with the piston and piston rod connected thereto, of equilibrated means for transforming the linear motion of the piston into rotary motion, comprising two parallel plates disposed upon oppcsite sides of the path of the piston. rod and mounted for rotation, each ofsaid plates carrying on its opposite faces oppositely arranged eccentrics, means connccting the eccentrics on the inner faces of the plates with the piston rod, said means cooperating with said eccentrics to trans form the linear motion of the piston rod into rotary motion about said plates, and a counterpoise connected to and movable with the eccentric on the outer faces of said plates.

2. A construction asset forth in claim 1, in which the means connecting the piston rod with the eccentrics on the inner faces of the plates comprise a slide lined to the piston rod and guided in a slideway arranged between said plates, a ring encircling each of said eccentrics, ball bearings interposed between each ring and its eccentric, and axles extending from opposite sides of said slide and connected to said rings.

3. A" construction as set forth in claim 1, in which the counterpoise consists of a sin itheplates, the means connecting the piston 10 rod with the eccentrics on the inner Faces of said plates comprising a slide radially connected to the piston rod and guioed in said slideway and the counterpoisc consisting of a single weight also guided in said slideW-ay. 15 Intestiinony whereof, I have signed my name to this specification.
